SPECIFICATION forming part Of Letters Patent NO. 421,385, dated February18, 1890.

' Application filed April 22, 1889. $eria1 No. 308,082. (No model.)

To all whom, it may concern:

Be it known that I, CYRUS CHAMBERS, .112, a citizen of the UnitedStates, residing; at Wynnewood, in the county of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements inBrick- Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, of whichFigure 1 is a plan view of the receiving end of a brick-machineoff-bearing belt and adjuncts embodying my invention, the adjacent endof the cut-off frame and belt being shown. Fig. 2 is a side elevationthereof. Fig. 8 is a transverse section through the off-bearing belt,&c., taken at a point where the brick is nearly edged. Figs. 4t and 5are like sections through the belt and its supporting-bar, showing thelatter curved and plane, respectively.

This invention relates to an improvement in brick-machines, and moreparticularly in the off-bearing belts thereof, whereby the bricks whendelivered upon said belts will be set on edge by the latter, and thus bein position to be removed by the off-bearers without liability of theside edges of the bricks being marred or defaced. Mechanism foreffecting such edging of the bricks is illustrated in Letters Patent No.301,4.71, granted July 8, 1884:, to George 11. Aregood, (andsubsequently assigned to me,) to which patent reference may be had, saidmechanism consisting of a supplementary inclined or twisted beltarranged with respect to the usual off-bearing belt, together with aguide for deflecting the advancing bricks upon said supplementary belt,whereby the latter takes up the bricks and redelivers the same edgewiseupon the off-bearing belt.

My invention has for its object to accomplish this edging of the bricksin a more perfect, simple, and less violent manner; and to this end itconsists, primarily, in a certain arrangement of the off-bearing beltwhereby it shall directly perform such edging; also, in a certainguard-frame disposed with relation to the said belt; also, in a beltsupporting bar of peculiar construction, all of which will be hereinafterfully described and definitely claimed.

Referring to the annexed drawings, A represents the receiving end of anoft-bearing usual manner.

belt of a brick-machine-such, for example, as the well-known Chambersmachine shown and described in various Letters Patent of the UnitedStates. This belt passes around the tightener-pulleys B O and around thepulleyD on the end of the cut-off frame E in the It is then passedaround a forward upright pulley F, whose shaft is journaled in a box fin the off-bearing frame G, said pulley being slightly elevated abovethe latter, as seen in Fig. 2. This pulleyF gives the belt aquarter-turn at ctt'. e., changing ;it from a horizontal to a verticalplane. The ;belt is then passed back and around a horizontal pulley H,mounted at the end of the frame E, which pulley returns the belt to ahorizontal plane, as at In such position it proceeds under thequarter-turned portion Ct as appearing, and on out in the usual manner,to the end of the 0ff-bearing frame any desired distance. It will beobserved that these pulleys stand so that their leading sides line withthe approaching belt, as is common with quarter-turn belt-pulleys.

The operation is as follows: The bricks are delivered from the cut-offbelt I at short intervals apart upon the off-bearing belt A, which isdriven at a greater speed than the former belt in the usual andwell-known way. The belt A carries the bricks forward, and as theyapproach the pulley F they are gradually inclined toward the lowerhorizontal portion a of thebelt till they reach a certain point,wherethey are carried along by both belt portions moving in unison, and theincline is sufficient to up-cdge the bricks, whereupon they are 'delivered wholly upon the horizontal portion a of the belt, as clearlyshown.

It will sometimes happen when the machine is running at a high rate ofspeed, making, say, one hundred bricks per minute, that the bricks willbe thrown with such force by and from the twisted portion of the belt asto fall over beyond a perpendicular, (indicated by dotted lines in Fig.3,) and thus drop sidewise upon or even drop entirely off the belt. To

remedy this defect, I arrange above the outer edge of the belt-section anear the perpendicular of the twisted section, a guard-piece J, of woodor other suitable material, which is supported in brackets j, that areadjustably secured to the side of the off-bearing frame bymeans of bolts7' passing through slots j in said brackets.

I sometimes secure to the frame E, adjacent to the upper twisted portiona of the belt, a correspondingly-twisted bar K, which is designed tosupport the latter. Although this bar may be flat in cross-section, asshown in Fig. 5, I prefer to curve or convex its bearingface, as thebelt will conform to the curvature, and thus relieve the corners of thebricks from under pressure and prevent marring thereof.

Having thus described my invention, I claim as new and wish to secure byLetters Patent- 1. In a brick-machine, the off-bearing belt having theinclined or twisted first receivingsection upon which the bricks arewholly delivered and theadjacent horizontal section upon which thebricks are edgewise deposited by said first receiving-section,substantially as described.

2. In abrick-machine, the combination,with the cut-off and otf-bearin gframes, of the horizontal pulleys D and Hand the upright pulley F,arranged with reference to each other substantially as shown anddescribed, and the single off-bearing belt with its inclined or twistedfirst receiving-section a and the adjacent horizontal section (1substantially as set forth.

3. In abrick-machine, the combination,with the off-bearing frame and theoff-bearing belt provided with the inclined or twisted section a and theadjacent horizontal section, of the guard-frame, arranged with relationto said sections substantially as described.

at. The combination, in a brick-machine, with the off-bearing frame andthe off-bearing belt provided with the inclined or twisted section a,and the adjacent horizontal section (1 of the guard-frame arranged withrelation to said sections and consisting of a longitudinal bar J,supported in slotted brackets j, adj ustably connected by means of boltsj with the side of the off-bearing frame, substantially as described.

5. In a brick-machine, the combination,with the off-bearin g frame andthe twisted ofi-bearing belt mounted thereon, of acorrespondingly-twisted supporting-bar secured to said frame withrespect to the belt, substantially CYRUS CHAMBERS, JR. \Vitnesses:
